I had my Savage Axis II HB in .223 out today... here's what I'm noticing...

The mag holds 4 rounds.

When I fill it with 4, the first round feeds properly as does the second. But, the third gets hung up as the bullet hits the top of the chamber. The fourth feeds fine.

When I fill it with 3, the first round feeds properly but the second does what is described above. The final third round feeds fine.

Also, I don't quite know the pattern yet... but I think it's the 2nd and/or 3rd round when filling the mag with 4 rounds... or, when filling it with 3, it's the 2nd round... but they're not extracting... they get pulled maybe a quarter of the way out but don't get thrown out of the gun. I recently switched from 55 grain Fiocchi FMJBT to 55 grain Hornady American Gunner HP. No extraction issues with the Fiocchi but it's happening with the Hornady.

Anyways... any help would be appreciated. Thanks!
